2x*7x=14

Solution for 2x*7x=14 equation:

2x*7x=14

We move all terms to the left:

2x*7x-(14)=0

Wy multiply elements

14x^2-14=0

a = 14; b = 0; c = -14;
Δ = b2-4ac
Δ = 02-4·14·(-14)
Δ = 784
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{784}=28$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-28}{2*14}=\frac{-28}{28}
=-1
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+28}{2*14}=\frac{28}{28}
=1
